abstract="BACKGROUND: Betel quid (BQ), chewed by about 600 million people worldwide, is one of the most widely used addictive substances. Little is known about psychological factors in BQ chewers. <br><br>OBJECTIVES: The present study was the first attempt to explore the relationships between BQ chewing, personality, and mood. <br><br>METHODS: A survey was conducted with a purposive sample to assess BQ chewing habits in four subgroups: BQ-only users, BQ users who smoke and/or drink, smokers and/or drinkers only, and substance nonusers. A total of 494 participants were recruited from the civilian, non-institutionalized population in Taiwan. Habitual consumption of BQ, smoking and drinking; socio-demographic variables; extraversion; and mood (tension, depression, anger, vigor, fatigue, confusion, and self-esteem). All BQ chewers were evaluated on BQ dependence domains using DSM IV and ICD-10 criteria. <br><br>RESULTS: The 6-month BQ dependency rate among BQ chewers, defined by either DSM-IV or ICD-10 criteria, ranged from 42.9 to 45.6%. BQ-only users had significantly lower scores on extraversion than substance nonusers. BQ-only users had statistically significant higher scores on confusion and total mood than substance nonusers. BQ-only users had significantly higher scores on fatigue, anger, tension, and depression, than substance nonusers, BQ users who smoke and/or drink, and smokers and/or drinkers only. The number of BQ dependence domains correlated significantly negatively with total mood scores. <br><br>CONCLUSIONS/Importance: The results supported the two hypotheses: (a) BQ chewing is associated with low extraversion; and (b) BQ chewing is related to negative mood.<p /> <p>Language: en</p>",
